RALPH IV. J ORRE3, OF THOMASTON, CONNECTICUT.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 409,406, dated August20, 1889.

Application filed May 4, 1889.

To to whom, it may concern.-

Be itknown that I, RALPH \VILLIAM JORRES, of Thomastoinin the county ofLitchfield and State of Connecticut, have invented a new and ImprovedShutter-Operating Device, of which the following is a full, clear, andexact description.

The object of this invention is to provide a shutter-operating device bymeans of which the shutter may be opened or closed without raising thesash, and which shall be so arranged that when the shutter is openeditwill be held against accidental displacement.

To the end named the invention consists, essentially, of a bracketformed with an upwardly-extending pintle and provided with a bearing foran operating-shaft, a segmental gear carried by the operating-shaft, anda segmental gear carried by the shutter, the bracket'pintle passingthrough the axis of said gear, the disk upon which the shaft-gear isformed having an eccentric bearing-face upon the side opposite that uponwhich the gear is formed, all as will be hereinafter more fullydescribed, and specifically pointed out in the claims.

Reference is to behad to the accompanying drawings, forming a part ofthis specification, in which similar figures and letters of referenceindicate corresponding parts in all the views.

Figure 1 is a view of my shutier-operating device, the shutter beingrepresented as it appears when in the open position, parts being brokenaway. Fig. 2 is a sectional view on line w w of Fig. 1. Fig. 3 is a planview of theopcrating device. Fig. at is a view of the outer end of theoperating-shaft and the parts carried thereby, and Fig. 5 is aperspective view of a portion of a window-framerepresenting the same asit appears when provided with my improved shutter-operating device.

In the drawings, represents a bracket which is secured to thewindow-casing as rcpresented in Fig. 1. This bracket is provided with anupwardly-extending pintle 11, with a stop or limit plate 12, and with arecess a, which serves as a bearin g for the outer end of a shaft 13,which extends inward through the win- (low-casing and is formed with asquared section 14, upon which an operating-handle may be mounted. Theshaft 13 carries a segmental Serial No. 309,611. (No model.)

gear 15 upon one side, while upon the other side there is formed aneccentric section I), having a flange c. To the corner of the shutter orblind (which is shown at there is secured a horizontal disk 21, formedwith a segmental bevel-gear 22, the disk 21 being centrally apertured toreceive the pintle 11.

In order that the shutters may be held in their open or closedpositions, I provide keepers and 50, that are arranged as shown in Fig.5, and formed with vertical flanges 0.

The parts constructed as above described are connected as represented inthe drawings. Then if the shaft 13 be turned in the direction of thearrow shown in connection therewith the gear 15 will engage the gear 22,and the shutter will be swung inward to the closed position, the initialmovement of the shaft 13 acting to raise the shutter vertically,inasmuch as when the shaft 13 first starts to turn the eccentric face ofthe flange 0 will bear upon the under side of the disk 21, and thisvertical movement of the shutter will carry it clear of its outer keeper50. Then after the shutter has been moved to a closed position the gear15 will pass from engagement with the gear 22, and the eccentric flange0 will once more bear upon the under side of the disk 21 and permit theshutter to gravitate to its lower position within the line of the flange0 of the keeper 50. The range of motion of the shaft- 13 is limited by astop f, which is arranged as shown in Figs. 1 and 4, said step strikingagainst the stop 12, that is carried by the bracket 10, as will bereadily understood.

By means of this shutter-operating device I am able to open or close theshutters or blinds from the inside, and it will be noticed that the saidshutters or blinds will be securely locked in either their open orclosed positions.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a sluitter-worker, the combination, with asegmental gear arranged for connection with a shutter, of a shaftcarrying a segmental gear for engaging the teeth of the segmental gearcarried by the shutter, and an eccentric bearing-face opposite thesegmental gear for engaging the under side of the said segmental gearcarried by the shutter before and after the gears are in and out ofengagement, whereby the shutter will be raised prior to being swung to aclosed position and lowered when in the closed position, substantiallyas and for the purpose set forth.

2. In a shutteroperating device, the combination, with a disk formedwith a segmental gear and arranged for connection with a shutter, of abracket formed with an upwardlyextending pintle which passes through theshutter-disk at a point coincident with the axis of the gear, a shaftcarrying a gear 15, having an eccentric-faced flange 'c, the outer endof the shaft being supported in a bearing formed in the bracket,substantially as described.

3. I11 a shutter-operating device, the combination, with a disk formedwith a segmental gear and arranged for connection with a shutter, of abracket formed with an upwardlyextending pintle which passes through theshutter-disk at a point coincident with the axis of the gear, a stopcarried by the bracket, a shaft provided with a segmental gear, and aneccentric flange having a stop, the outer end of the shaft beingsupportedin a bearing formed in the bracket, substantially as described.
